Help Optimizing Plots

Hey, I'm currently trying to optimize my plots. But it doesn't seem to be working... I'm using this plot optimizer with gui http://imgur.com/a/cawXW . The optimizer doesn't go beyond "Estimating Time Remaining". I've plotted my plots with the AIO client; I've also read somewhere that the AIO Plotter
optimizes plots as well as plots them (Not too sure). Could that be the case? Thanks for all the feedback!

RE: Also I noticed that in the bottom left of the optimizer it says "File is already optimized". Does that mean it's legitimately optimized already? If so would it be because of the AIO plotter? Thanks
